MOLLUSCA.

Limnophila. 
Auriculid^. 
The observation made by the Recorder, that the species of this family live 
on muddy ground in brackish water, is fully confirmed by Blanford in his 
paper on the estuary mollusks of the Irawady (Journ. As. Soc. Beng. ii. p. 02). 
There are two exceptions from this rule, viz. the genus Carychium, which 
lives in the middle of continents, and Pedipes^ which lives on rocks exposed 
to the open sea, in company with Litorina, os has been observed by the Re- 
corder, Breuss. Exped. Zool. i. p. 14.

Auricida. The absence of eyes in Aur. judcc, stated by Eydoux and the 
Recorder, is confirmed by Blanford, as well as their existence m Aurietda 
suhula (Q. & G.), Journ. As. Soc. ii. p. 63. [The Recorder thinks that the 
latter may be transferred to the genus or subgenuS Alexia and the name Au7'i- 
cmZm retained for the large blind species, ^%judce and midee^ There is a com- 
plete passage from A.judce into dactylus (Pfr.),'‘Blanford, 1. c. p. 64. [Also A. 
turrita (Pfr.) and polita (Metcalfe) may safely be regarded as individual 
varieties oijudee.']
